 2113-2247 1.29e-69

p63RhoGEF pleckstrin homology (PH) domain, repeat 2; The guanine nucleotide exchange factor p63RhoGEF is an effector of the heterotrimeric G protein, Galphaq and linking Galphaq-coupled receptors (GPCRs) to the activation of RhoA. The Dbl(DH) and PH domains of p63RhoGEF interact with the effector-binding site and the C-terminal region of Galphaq and appear to relieve autoinhibition of the catalytic DH domain by the PH domain. Trio, Duet, and p63RhoGEF are shown to constitute a family of Galphaq effectors that appear to activate RhoA both in vitro and in intact cells. Dbs is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Trio is a multidomain signaling protein that contains two RhoGEF(DH)-PH domains in tandem. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

 1469-1591 9.67e-69

Triple functional domain pleckstrin homology pleckstrin homology (PH) domain, repeat 1; RhoGEFs, Kalirin and Trio, the mammalian homologs of Drosophila Trio and Caenorhabditis elegans UNC-73 regulate a novel step in secretory granule maturation. Their signaling modulates the extent to which regulated cargo enter and remain in the regulated secretory pathway. This allows for fine tuning of peptides released by a single secretory cell type with impaired signaling leading to pathological states. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Kalirin and Trio are encoded by separate genes in mammals and by a single one in invertebrates. Kalirin and Trio share the same complex multidomain structure and display several splice variants. The longest Kalirin and Trio proteins have a Sec14 domain, a stretch of spectrin repeats, a RhoGEF(DH)/PH cassette (also called GEF1), an SH3 domain, a second RhoGEF(DH)/PH cassette (also called GEF2), a second SH3 domain, Ig/FNIII domains, and a kinase domain. The first RhoGEF(DH)/PH cassette catalyzes exchange on Rac1 and RhoG while the second RhoGEF(DH)/PH cassette is specific for RhoA. Kalirin and Trio are closely related to p63RhoGEF and have PH domains of similar function. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains.

 2331-2387 4.60e-32

Second Src homology 3 domain of the RhoGEF kinase, Kalirin; Kalirin, also called Duo, Duet, or TRAD, is a large neuronal dual Rho guanine nucleotide exchange factor (RhoGEF) that activates Rac1, RhoA, and RhoG using two RhoGEF domains. Kalirin exists in many isoforms generated by alternative splicing and the use of multiple promoters; the major isoforms are kalirin-7, -9, and -12, which differ at their C-terminal ends. Kalirin-12, the longest isoform, contains an N-terminal Sec14p domain, spectrin-like repeats, two RhoGEF domains, two SH3 domains, as well as Ig, FNIII, and kinase domains at the C-terminal end. Kalirin-7 contains only a single RhoGEF domain and does not contain an SH3 domain. Kalirin, through its many isoforms, interacts with many different proteins and is able to localize to different locations within the cell. It influences neurite initiation, axon growth, dendritic morphogenesis, vesicle trafficking, neuronal maintenance, and neurodegeneration. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

 2113-2247 1.29e-69

p63RhoGEF pleckstrin homology (PH) domain, repeat 2; The guanine nucleotide exchange factor p63RhoGEF is an effector of the heterotrimeric G protein, Galphaq and linking Galphaq-coupled receptors (GPCRs) to the activation of RhoA. The Dbl(DH) and PH domains of p63RhoGEF interact with the effector-binding site and the C-terminal region of Galphaq and appear to relieve autoinhibition of the catalytic DH domain by the PH domain. Trio, Duet, and p63RhoGEF are shown to constitute a family of Galphaq effectors that appear to activate RhoA both in vitro and in intact cells. Dbs is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Trio is a multidomain signaling protein that contains two RhoGEF(DH)-PH domains in tandem. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Triple functional domain pleckstrin homology pleckstrin homology (PH) domain, repeat 1; RhoGEFs, Kalirin and Trio, the mammalian homologs of Drosophila Trio and Caenorhabditis elegans UNC-73 regulate a novel step in secretory granule maturation. Their signaling modulates the extent to which regulated cargo enter and remain in the regulated secretory pathway. This allows for fine tuning of peptides released by a single secretory cell type with impaired signaling leading to pathological states. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Kalirin and Trio are encoded by separate genes in mammals and by a single one in invertebrates. Kalirin and Trio share the same complex multidomain structure and display several splice variants. The longest Kalirin and Trio proteins have a Sec14 domain, a stretch of spectrin repeats, a RhoGEF(DH)/PH cassette (also called GEF1), an SH3 domain, a second RhoGEF(DH)/PH cassette (also called GEF2), a second SH3 domain, Ig/FNIII domains, and a kinase domain. The first RhoGEF(DH)/PH cassette catalyzes exchange on Rac1 and RhoG while the second RhoGEF(DH)/PH cassette is specific for RhoA. Kalirin and Trio are closely related to p63RhoGEF and have PH domains of similar function. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains.

 2331-2387 4.60e-32

Second Src homology 3 domain of the RhoGEF kinase, Kalirin; Kalirin, also called Duo, Duet, or TRAD, is a large neuronal dual Rho guanine nucleotide exchange factor (RhoGEF) that activates Rac1, RhoA, and RhoG using two RhoGEF domains. Kalirin exists in many isoforms generated by alternative splicing and the use of multiple promoters; the major isoforms are kalirin-7, -9, and -12, which differ at their C-terminal ends. Kalirin-12, the longest isoform, contains an N-terminal Sec14p domain, spectrin-like repeats, two RhoGEF domains, two SH3 domains, as well as Ig, FNIII, and kinase domains at the C-terminal end. Kalirin-7 contains only a single RhoGEF domain and does not contain an SH3 domain. Kalirin, through its many isoforms, interacts with many different proteins and is able to localize to different locations within the cell. It influences neurite initiation, axon growth, dendritic morphogenesis, vesicle trafficking, neuronal maintenance, and neurodegeneration. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

 319-418 3.29e-07

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

Pleckstrin homology domain; Domain commonly found in eukaryotic signalling proteins. The domain family possesses multiple functions including the abilities to bind inositol phosphates, and various proteins. PH domains have been found to possess inserted domains (such as in PLC gamma, syntrophins) and to be inserted within other domains. Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

p63RhoGEF pleckstrin homology (PH) domain, repeat 2; The guanine nucleotide exchange factor p63RhoGEF is an effector of the heterotrimeric G protein, Galphaq and linking Galphaq-coupled receptors (GPCRs) to the activation of RhoA. The Dbl(DH) and PH domains of p63RhoGEF interact with the effector-binding site and the C-terminal region of Galphaq and appear to relieve autoinhibition of the catalytic DH domain by the PH domain. Trio, Duet, and p63RhoGEF are shown to constitute a family of Galphaq effectors that appear to activate RhoA both in vitro and in intact cells. Dbs is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Trio is a multidomain signaling protein that contains two RhoGEF(DH)-PH domains in tandem. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Triple functional domain pleckstrin homology pleckstrin homology (PH) domain, repeat 1; RhoGEFs, Kalirin and Trio, the mammalian homologs of Drosophila Trio and Caenorhabditis elegans UNC-73 regulate a novel step in secretory granule maturation. Their signaling modulates the extent to which regulated cargo enter and remain in the regulated secretory pathway. This allows for fine tuning of peptides released by a single secretory cell type with impaired signaling leading to pathological states. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Kalirin and Trio are encoded by separate genes in mammals and by a single one in invertebrates. Kalirin and Trio share the same complex multidomain structure and display several splice variants. The longest Kalirin and Trio proteins have a Sec14 domain, a stretch of spectrin repeats, a RhoGEF(DH)/PH cassette (also called GEF1), an SH3 domain, a second RhoGEF(DH)/PH cassette (also called GEF2), a second SH3 domain, Ig/FNIII domains, and a kinase domain. The first RhoGEF(DH)/PH cassette catalyzes exchange on Rac1 and RhoG while the second RhoGEF(DH)/PH cassette is specific for RhoA. Kalirin and Trio are closely related to p63RhoGEF and have PH domains of similar function. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains.

 2331-2387 4.60e-32

Second Src homology 3 domain of the RhoGEF kinase, Kalirin; Kalirin, also called Duo, Duet, or TRAD, is a large neuronal dual Rho guanine nucleotide exchange factor (RhoGEF) that activates Rac1, RhoA, and RhoG using two RhoGEF domains. Kalirin exists in many isoforms generated by alternative splicing and the use of multiple promoters; the major isoforms are kalirin-7, -9, and -12, which differ at their C-terminal ends. Kalirin-12, the longest isoform, contains an N-terminal Sec14p domain, spectrin-like repeats, two RhoGEF domains, two SH3 domains, as well as Ig, FNIII, and kinase domains at the C-terminal end. Kalirin-7 contains only a single RhoGEF domain and does not contain an SH3 domain. Kalirin, through its many isoforms, interacts with many different proteins and is able to localize to different locations within the cell. It influences neurite initiation, axon growth, dendritic morphogenesis, vesicle trafficking, neuronal maintenance, and neurodegeneration. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

p63RhoGEF pleckstrin homology (PH) domain, repeat 2; The guanine nucleotide exchange factor p63RhoGEF is an effector of the heterotrimeric G protein, Galphaq and linking Galphaq-coupled receptors (GPCRs) to the activation of RhoA. The Dbl(DH) and PH domains of p63RhoGEF interact with the effector-binding site and the C-terminal region of Galphaq and appear to relieve autoinhibition of the catalytic DH domain by the PH domain. Trio, Duet, and p63RhoGEF are shown to constitute a family of Galphaq effectors that appear to activate RhoA both in vitro and in intact cells. Dbs is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Trio is a multidomain signaling protein that contains two RhoGEF(DH)-PH domains in tandem. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Puratrophin-1 pleckstrin homology (PH) domain; Puratrophin-1 (also called Purkinje cell atrophy-associated protein 1 or PLEKHG4/Pleckstrin homology domain-containing family G member 4) contains a spectrin repeat, a RhoGEF (DH) domain, and a PH domain. It is thought to function in intracellular signaling and cytoskeleton dynamics at the Golgi. Puratrophin-1 is expressed in kidney, Leydig cells in the testis, epithelial cells in the prostate gland and Langerhans islet in the pancreas. A single nucleotide substitution in the puratrophin-1 gene were once thought to result in autosomal dominant cerebellar ataxia (ADCA), but now it has been demonstrated that this ataxia is a result of defects in the BEAN gene. Puratrophin contains a domain architecture similar to that of Dbl family members Dbs and Trio.

 1469-1590 1.14e-16

Obscurin pleckstrin homology (PH) domain; Obscurin (also called Obscurin-RhoGEF; Obscurin-myosin light chain kinase/Obscurin-MLCK) is a giant muscle protein that is concentrated at the peripheries of Z-disks and M-lines. It binds small ankyrin I, a component of the sarcoplasmic reticulum (SR) membrane. It is associated with the contractile apparatus through binding with titin and sarcomeric myosin. It plays important roles in the organization and assembly of the myofibril and the SR. Obscurin has been observed as alternatively-spliced isoforms. The major isoform in sleletal muscle, approximately 800 kDa in size, is composed of many adhesion modules and signaling domains. It harbors 49 Ig and 2 FNIII repeats at the N-terminues, a complex middle region with additional Ig domains, an IQ motif, and a conserved SH3 domain near RhoGEF and PH domains, and a non-modular C-terminus with phosphorylation motifs. The obscurin gene also encodes two kinase domains, which are not part of the 800 kDa form of the protein, but is part of smaller spliced products that present in heart muscle. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

DBL's big sister protein pleckstrin homology (PH) domain; Dbs (also called MCF2-transforming sequence-like protein 2) is a guanine nucleotide exchange factor (GEF), which contains spectrin repeats, a rhoGEF (DH) domain and a PH domain. The Dbs PH domain participates in binding to both the Cdc42 and RhoA GTPases. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Triple functional domain pleckstrin homology pleckstrin homology (PH) domain, repeat 1; RhoGEFs, Kalirin and Trio, the mammalian homologs of Drosophila Trio and Caenorhabditis elegans UNC-73 regulate a novel step in secretory granule maturation. Their signaling modulates the extent to which regulated cargo enter and remain in the regulated secretory pathway. This allows for fine tuning of peptides released by a single secretory cell type with impaired signaling leading to pathological states. Trio plays an essential role in regulating the actin cytoskeleton during axonal guidance and branching. Kalirin and Trio are encoded by separate genes in mammals and by a single one in invertebrates. Kalirin and Trio share the same complex multidomain structure and display several splice variants. The longest Kalirin and Trio proteins have a Sec14 domain, a stretch of spectrin repeats, a RhoGEF(DH)/PH cassette (also called GEF1), an SH3 domain, a second RhoGEF(DH)/PH cassette (also called GEF2), a second SH3 domain, Ig/FNIII domains, and a kinase domain. The first RhoGEF(DH)/PH cassette catalyzes exchange on Rac1 and RhoG while the second RhoGEF(DH)/PH cassette is specific for RhoA. Kalirin and Trio are closely related to p63RhoGEF and have PH domains of similar function. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains.

Pleckstrin homology domain-containing family G members 1, 2, and 3 pleckstrin homology (PH) domain; PLEKHG1 (also called ARHGEF41), PLEKHG2 (also called ARHGEF42 or CLG/common-site lymphoma/leukemia guanine nucleotide exchange factor2), and PLEKHG3 (also called ARHGEF43) have RhoGEF DH/double-homology domains in tandem with a PH domain which is involved in phospholipid binding. They function as a guanine nucleotide exchange factor (GEF) and are involved in the regulation of Rho protein signal transduction. Mutations in PLEKHG1 have been associated panic disorder (PD), an anxiety disorder characterized by panic attacks and anticipatory anxiety. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Obscurin pleckstrin homology (PH) domain; Obscurin (also called Obscurin-RhoGEF; Obscurin-myosin light chain kinase/Obscurin-MLCK) is a giant muscle protein that is concentrated at the peripheries of Z-disks and M-lines. It binds small ankyrin I, a component of the sarcoplasmic reticulum (SR) membrane. It is associated with the contractile apparatus through binding with titin and sarcomeric myosin. It plays important roles in the organization and assembly of the myofibril and the SR. Obscurin has been observed as alternatively-spliced isoforms. The major isoform in sleletal muscle, approximately 800 kDa in size, is composed of many adhesion modules and signaling domains. It harbors 49 Ig and 2 FNIII repeats at the N-terminues, a complex middle region with additional Ig domains, an IQ motif, and a conserved SH3 domain near RhoGEF and PH domains, and a non-modular C-terminus with phosphorylation motifs. The obscurin gene also encodes two kinase domains, which are not part of the 800 kDa form of the protein, but is part of smaller spliced products that present in heart muscle. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity.

 1660-1712 2.36e-07

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

 319-418 3.29e-07

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

 2334-2387 4.38e-07

First Src homology 3 domain of the RhoGEF kinase, Kalirin; Kalirin, also called Duo, Duet, or TRAD, is a large neuronal dual Rho guanine nucleotide exchange factor (RhoGEF) that activates Rac1, RhoA, and RhoG using two RhoGEF domains. Kalirin exists in many isoforms generated by alternative splicing and the use of multiple promoters; the major isoforms are kalirin-7, -9, and -12, which differ at their C-terminal ends. Kalirin-12, the longest isoform, contains an N-terminal Sec14p domain, spectrin-like repeats, two RhoGEF domains, two SH3 domains, as well as Ig, FNIII, and kinase domains at the C-terminal end. Kalirin-7 contains only a single RhoGEF domain and does not contain an SH3 domain. Kalirin, through its many isoforms, interacts with many different proteins and is able to localize to different locations within the cell. It influences neurite initiation, axon growth, dendritic morphogenesis, vesicle trafficking, neuronal maintenance, and neurodegeneration. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

 1658-1717 3.06e-06

Src homology 3 domain of yeast cell fusion protein Fus1p; Fus1p is required at the cell surface for cell fusion during the mating response in yeast. It requires Bch1p and Bud7p, which are Chs5p-Arf1p binding proteins, for localization to the plasma membrane. It acts as a scaffold protein to assemble a cell surface complex which is involved in septum degradation and inhibition of the NOG pathway to promote cell fusion. The SH3 domain of Fus1p interacts with Bin1p, a formin that controls the assembly of actin cables in response to Cdc42 signaling. It has been shown to bind the motif, R(S/T)(S/T)SL, instead of PxxP motifs. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

Pleckstrin homology domain; Domain commonly found in eukaryotic signalling proteins. The domain family possesses multiple functions including the abilities to bind inositol phosphates, and various proteins. PH domains have been found to possess inserted domains (such as in PLC gamma, syntrophins) and to be inserted within other domains. Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

 1481-1589 4.73e-06

unc89 pleckstrin homology (PH) domain; unc89 is a myofibrillar protein. unc89-B the largest isoform is composed of 53 immunoglobulin (Ig) domains, 2 Fn3 domains, a triplet of SH3, DH and PH domains at its N-terminus, and 2 protein kinase domains (PK1 and PK2) at its C-terminus. unc-89 mutants display disorganization of muscle A-bands, and usually lack M-lines. The COOH-terminal region of obscurin, the human homolog of unc89, interacts via two specific Ig-like domains with the NH(2)-terminal Z-disk region of titin, a protein that connects the Z line to the M line in the sarcomere and contributes to the contraction of striated muscle. obscurin is also thought to be involved in Ca2+/calmodulin via its IQ domains, as well as G protein-coupled signal transduction in the sarcomere via its RhoGEF/DH domain. The DH-PH region of OBSCN and unc89, the C. elegans homolog, has exchange activity for RhoA and Rho-1 respectively, but not for the small GTPases homologous to Cdc42 or Rac. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

 1660-1714 7.10e-06

Src homology 3 domains of the p47phox subunit of NADPH oxidase and similar domains; This family is composed of the tandem SH3 domains of p47phox subunit of NADPH oxidase and Nox Organizing protein 1 (NoxO1), the four SH3 domains of Tks4 (Tyr kinase substrate with four SH3 domains), the five SH3 domains of Tks5, the SH3 domain of obscurin, Myosin-I, and similar domains. Most members of this group also contain Phox homology (PX) domains, except for obscurin and Myosin-I. p47phox and NoxO1 are regulators of the phagocytic NADPH oxidase complex (also called Nox2 or gp91phox) and nonphagocytic NADPH oxidase Nox1, respectively. They play roles in the activation of their respective NADPH oxidase, which catalyzes the transfer of electrons from NADPH to molecular oxygen to form superoxide. Tks proteins are Src substrates and scaffolding proteins that play important roles in the formation of podosomes and invadopodia, the dynamic actin-rich structures that are related to cell migration and cancer cell invasion. Obscurin is a giant muscle protein that plays important roles in the organization and assembly of the myofibril and the sarcoplasmic reticulum. Type I myosins (Myosin-I) are actin-dependent motors in endocytic actin structures and actin patches. They play roles in membrane traffic in endocytic and secretory pathways, cell motility, and mechanosensing. Myosin-I contains an N-terminal actin-activated ATPase, a phospholipid-binding TH1 (tail homology 1) domain, and a C-terminal extension which includes an F-actin-binding TH2 domain, an SH3 domain, and an acidic peptide that participates in activating the Arp2/3complex. The SH3 domain of myosin-I is required for myosin-I-induced actin polymerization. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

First Src Homology 3 domain of Bzz1 and similar domains; Bzz1 (or Bzz1p) is a WASP/Las17-interacting protein involved in endocytosis and trafficking to the vacuole. It physically interacts with type I myosins and functions in the early steps of endocytosis. Together with other proteins, it induces membrane scission in yeast. Bzz1 contains an N-terminal F-BAR (FES-CIP4 Homology and Bin/Amphiphysin/Rvs), a central coiled-coil, and two C-terminal SH3 domains. This model represents the first C-terminal SH3 domain. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

It binds and regulates some members of the ADAMs family of transmembrane metalloproteases, which function as sheddases and mediators of cell and matrix interactions. It is required for podosome formation, degradation of the extracellular matrix, and cancer cell invasion. Tks5 contains an N-terminal Phox homology (PX) domain and five SH3 domains. This model characterizes the first SH3 domain of Tks5. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

First Src homology 3 domain of Tyrosine kinase substrate with four SH3 domains; Tks4, also called SH3 and PX domain-containing protein 2B (SH3PXD2B) or HOFI, is a Src substrate and scaffolding protein that plays an important role in the formation of podosomes and invadopodia, the dynamic actin-rich structures that are related to cell migration and cancer cell invasion. It is required in the formation of functional podosomes, EGF-induced membrane ruffling, and lamellipodia generation. It plays an important role in cellular attachment and cell spreading. Tks4 is essential for the localization of MT1-MMP (membrane-type 1 matrix metalloproteinase) to invadopodia. It contains an N-terminal Phox homology (PX) domain and four SH3 domains. This model characterizes the first SH3 domain of Tks4. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

 198-316 1.63e-04

Spectrin repeat; Spectrin repeat-domains are found in several proteins involved in cytoskeletal structure. These include spectrin, alpha-actinin and dystrophin. The sequence repeat used in this family is taken from the structural repeat in reference. The spectrin domain- repeat forms a three helix bundle. The second helix is interrupted by proline in some sequences. The repeats are defined by a characteriztic tryptophan (W) residue at position 17 in helix A and a leucine (L) at 2 residues from the carboxyl end of helix C. Although the domain occurs in multiple repeats along sequences, the domains are actually stable on their own - ie they act, biophysically, like domains rather than repeats that along function when aggregated.

Pleckstrin homology domain; Domain commonly found in eukaryotic signalling proteins. The domain family possesses multiple functions including the abilities to bind inositol phosphates, and various proteins. PH domains have been found to possess inserted domains (such as in PLC gamma, syntrophins) and to be inserted within other domains. Mutations in Brutons tyrosine kinase (Btk) within its PH domain cause X-linked agammaglobulinaemia (XLA) in patients. Point mutations cluster into the positively charged end of the molecule around the predicted binding site for phosphatidylinositol lipids.

 2091-2231 1.93e-04

Pleckstrin homology domain-containing family G members 1, 2, and 3 pleckstrin homology (PH) domain; PLEKHG1 (also called ARHGEF41), PLEKHG2 (also called ARHGEF42 or CLG/common-site lymphoma/leukemia guanine nucleotide exchange factor2), and PLEKHG3 (also called ARHGEF43) have RhoGEF DH/double-homology domains in tandem with a PH domain which is involved in phospholipid binding. They function as a guanine nucleotide exchange factor (GEF) and are involved in the regulation of Rho protein signal transduction. Mutations in PLEKHG1 have been associated panic disorder (PD), an anxiety disorder characterized by panic attacks and anticipatory anxiety. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

unc89 pleckstrin homology (PH) domain; unc89 is a myofibrillar protein. unc89-B the largest isoform is composed of 53 immunoglobulin (Ig) domains, 2 Fn3 domains, a triplet of SH3, DH and PH domains at its N-terminus, and 2 protein kinase domains (PK1 and PK2) at its C-terminus. unc-89 mutants display disorganization of muscle A-bands, and usually lack M-lines. The COOH-terminal region of obscurin, the human homolog of unc89, interacts via two specific Ig-like domains with the NH(2)-terminal Z-disk region of titin, a protein that connects the Z line to the M line in the sarcomere and contributes to the contraction of striated muscle. obscurin is also thought to be involved in Ca2+/calmodulin via its IQ domains, as well as G protein-coupled signal transduction in the sarcomere via its RhoGEF/DH domain. The DH-PH region of OBSCN and unc89, the C. elegans homolog, has exchange activity for RhoA and Rho-1 respectively, but not for the small GTPases homologous to Cdc42 or Rac. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Src Homology 3 domain of GTPase Regulator Associated with Focal adhesion kinase and similar proteins; This subfamily is composed of Rho GTPase activating proteins (GAPs) with similarity to GRAF. Members contain an N-terminal BAR domain, followed by a Pleckstrin homology (PH) domain, a Rho GAP domain, and a C-terminal SH3 domain. Although vertebrates harbor four Rho GAPs in the GRAF subfamily including GRAF, GRAF2, GRAF3, and Oligophrenin-1 (OPHN1), only three are included in this model. OPHN1 contains the BAR, PH and GAP domains, but not the C-terminal SH3 domain. GRAF and GRAF2 show GAP activity towards RhoA and Cdc42. GRAF influences Rho-mediated cytoskeletal rearrangements and binds focal adhesion kinase. GRAF2 regulates caspase-activated p21-activated protein kinase-2. The SH3 domain of GRAF and GRAF2 binds PKNbeta, a target of the small GTPase Rho. SH3 domains bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs; they play a role in the regulation of enzymes by intramolecular interactions, changing the subcellular localization of signal pathway components and mediate multiprotein complex assemblies.

 1498-1590 2.60e-03

Collybistin/APC-stimulated guanine nucleotide exchange factor pleckstrin homology (PH) domain; Collybistin (also called PEM2) is homologous to the Dbl proteins ASEF (also called ARHGEF4/RhoGEF4) and SPATA13 (Spermatogenesis-associated protein 13; also called ASEF2). It activates CDC42 specifically and not any other Rho-family GTPases. Collybistin consists of an SH3 domain, followed by a RhoGEF/DH and PH domain. In Dbl proteins, the DH and PH domains catalyze the exchange of GDP for GTP in Rho GTPases, allowing them to signal to downstream effectors. It induces submembrane clustering of the receptor-associated peripheral membrane protein gephyrin, which is thought to form a scaffold underneath the postsynaptic membrane linking receptors to the cytoskeleton. It also acts as a tumor suppressor that links adenomatous polyposis coli (APC) protein, a negative regulator of the Wnt signaling pathway and promotes the phosphorylation and degradation of beta-catenin, to Cdc42. Autoinhibition of collybistin is accomplished by the binding of its SH3 domain with both the RhoGEF and PH domains to block access of Cdc42 to the GTPase-binding site. Inactivation promotes cancer progression. PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

Third Src Homology 3 domain of Nck adaptor proteins; This group contains the third SH3 domain of Nck, the first SH3 domain of Caenorhabditis elegans Ced-2 (Cell death abnormality protein 2), and similar domains. Nck adaptor proteins regulate actin cytoskeleton dynamics by linking proline-rich effector molecules to protein tyrosine kinases and phosphorylated signaling intermediates. They contain three SH3 domains and a C-terminal SH2 domain. They function downstream of the PDGFbeta receptor and are involved in Rho GTPase signaling and actin dynamics. Vertebrates contain two Nck adaptor proteins: Nck1 (also called Nckalpha) and Nck2 (also called Nckbeta or Growth factor receptor-bound protein 4, Grb4), which show partly overlapping functions but also bind distinct targets. Their SH3 domains are involved in recruiting downstream effector molecules, such as the N-WASP/Arp2/3 complex, which when activated induces actin polymerization that results in the production of pedestals, or protrusions of the plasma membrane. The third SH3 domain of Nck appears to prefer ligands with a PxAPxR motif. SH3 domains are protein interaction domains that usually bind to proline-rich ligands with moderate affinity and selectivity, preferentially a PxxP motif. Ced-2 is a cell corpse engulfment protein that interacts with Ced-5 in a pathway that regulates the activation of Ced-10, a Rac small GTPase.

chromosome segregation protein SMC, common bacterial type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. This family represents the SMC protein of most bacteria. The smc gene is often associated with scpB (TIGR00281) and scpA genes, where scp stands for segregation and condensation protein. SMC was shown (in Caulobacter crescentus) to be induced early in S phase but present and bound to DNA throughout the cell cycle.

 1658-1712 5.04e-03

Src Homology 3 domain of eumetazoan Peroxisomal biogenesis factor 13; PEX13 is a peroxin and is required for protein import into the peroxisomal matrix and membrane. It is an integral membrane protein that is essential for the localization of PEX14 and the import of proteins containing the peroxisome matrix targeting signals, PTS1 and PTS2. Mutations of the PEX13 gene in humans lead to a wide range of peroxisome biogenesis disorders (PBDs), the most severe of which is known as Zellweger syndrome (ZS), a severe multisystem disorder characterized by hypotonia, psychomotor retardation, and neuronal migration defects. PEX13 contains two transmembrane regions and a C-terminal SH3 domain. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

 1660-1714 5.17e-03

First Src homology 3 domain of Tyrosine kinase substrate (Tks) proteins; Tks proteins are Src substrates and scaffolding proteins that play important roles in the formation of podosomes and invadopodia, the dynamic actin-rich structures that are related to cell migration and cancer cell invasion. Vertebrates contain two Tks proteins, Tks4 (Tyr kinase substrate with four SH3 domains) and Tks5 (Tyr kinase substrate with five SH3 domains), which display partially overlapping but non-redundant functions. Both associate with the ADAMs family of transmembrane metalloproteases, which function as sheddases and mediators of cell and matrix interactions. Tks5 interacts with N-WASP and Nck, while Tks4 is essential for the localization of MT1-MMP (membrane-type 1 matrix metalloproteinase) to invadopodia. Tks proteins contain an N-terminal Phox homology (PX) domain and four or five SH3 domains. This model characterizes the first SH3 domain of Tks proteins. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.

 2136-2227 9.96e-03

Pleckstrin homology (PH) domain; PH domains have diverse functions, but in general are involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. Less than 10% of PH domains bind phosphoinositide phosphates (PIPs) with high affinity and specificity. PH domains are distinguished from other PIP-binding domains by their specific high-affinity binding to PIPs with two vicinal phosphate groups: PtdIns(3,4)P2, PtdIns(4,5)P2 or PtdIns(3,4,5)P3 which results in targeting some PH domain proteins to the plasma membrane. A few display strong specificity in lipid binding. Any specificity is usually determined by loop regions or insertions in the N-terminus of the domain, which are not conserved across all PH domains. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.

 1657-1712 9.96e-03

Third Src Homology 3 domain of the fungal endocytic adaptor protein Sla1p; Sla1p facilitates endocytosis by playing a role as an adaptor protein in coupling components of the actin cytoskeleton to the endocytic machinery. It interacts with Abp1p, Las17p and Pan1p, which are activator proteins of actin-related protein 2/3 (Arp2/3). Sla1p contains multiple domains including three SH3 domains, a SAM (sterile alpha motif) domain, and a Sla1 homology domain 1 (SHD1), which binds to the NPFXD motif that is found in many integral membrane proteins such as the Golgi-localized Arf-binding protein Lsb5p and the P4-ATPases, Drs2p and Dnf1p. The third SH3 domain of Sla1p can bind ubiquitin while retaining the ability to bind proline-rich ligands; monoubiquitination of target proteins signals internalization and sorting through the endocytic pathway. SH3 domains are protein interaction domains that bind to proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They play versatile and diverse roles in the cell including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies.
